To all whom it may concerm Be it knownthat I, BENJAMIN WoLnAU'rtainnew and useful Improvements in Insu- -lated Rail-Joints,of which the following is a view,. wh1ch will more readily appear to those specification.

' This invention relates to that class of rail joints embodying in their organization a sectional or two-part supporting base for the I rail ends whereby each. base section affords I one rail end a support on both sides of the e rail ends without con-- meeting point oft tact withthe corresponding baseplate sec tion.

'- 1T0 this-end theinvention contemplates an improvediail joint structure having the same general objects in view as those carried out in connection 'with the forms of insulated rail oints disclosed and claimed in companion applicationsfiled November, 8, 1906,-

and bearing Serial Numbers 342,523, and 342, 524. -At the same time the invention primarily vhasin view a'novel and 'efiective reorganization inthe construction of those types of angle bars characterized .as rein" forced angle bars, whereby -all of the desirable reinforcing features of bars of this ty may be preserved in connection with t e added functions of a two-part or sectional base plate construction wherein-a separate base plate section is arranged, to receive and sup ort one rail end in sucha manner that eac of said sections aflords one raile'nd a ort on both sidesof the meeting oint. .of t e railswithout'metallic'or electrical com tact with the corresponding base section.

. A-further gencral object of the invention-is to so arrange the separate base plate sections 'oint with t insulatin material.

A an a ob' ect' .of the. invention is to providela. nov'e i; and effective. arrangement;

.50; ratejbase supports, so ass-to,,accomplish the of theseparate' base plate sections; or"sep'aobjects above indicated; and-yet provide no; .-base' support resting on the-ties. In' tlns from the companion applications referred to, for inasmuch as wh1 e therr is a direct bearing of the rail on the metal of the reinforced bar, still the load applied thereon is not delivered to the ties directly, but through the insulation.

With these and many other objects in familiar withwthe art, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated, and claimed.

The'essential features of the invention in volved 1n the application of thetwo-part or sectional base plate construction to reinforced types of angle bars, are necessarily susceptible to a wide ran e of modification without departing from ti but certain preferred practical embodiments thereof are shown" in -the accompanying drawings, in which: I

Fig. 9is a side'elevation "similar :to Figs. land 6, illustrating another ffo'rm of rail joint,1of the reinforced angle bar *type,e m'b0dying thepresentinvention. Fig. 10 is an enlarged sectional view. on the-line '1010 of Fig; 9. Fig. 11 is a horizontal secvtionalview' on theline.1 1 -11"of Fig. 10 showing in plan, the base plate arrangement 'of the present invention resides in associating with splice bars or fish plates, of thereinforced angle bar type, a rail supporting base or base plate made in two sections or parts whereby each supporting base or base plate section receives thereon one rail end only, while at the same time each of said sections of the supporting base affords the rail end thereon a support on both sides of the meeting point of'the rail ends, and hence the support of the ties on both sides of said meeting point, without metallic or electrical contact with the corresponding section of the supporting base.

Also, in adapting the two-part or sectional rail supporting'base to angle bars of the reinforced type, the present invention presents the distinctive feature of an insulated rail joint wherein there is no base support resting on the ties, and though there is a direct bearing of each rail end on the metal of the reinforced bar, still the load applied thereon is not delivered to the ties directly, but through insulation. These features of construction may be utilized in a variety of ways and combined with divers forms'of rail joints having reinforced angle-bars without afiecting the scope or general purposes of the invention, but for illustrative purposes a few preferred forms of joints are shown in the drawings to exemplify the special features claimed, and particular reference will now be made to these forms.

Referring to the type of joint illustrated in Figs. 1 to 5 inclusive of the drawings, it will be observed that this joint includes in its construction-the adjacent service or run ning rails 1 and 2, the op ositely arranged side angle bars '3 and 4, an the joint bolts 5 passing through the usual bolt holes in the angle bars and in the webs of the rail ends.

' insulatmg washers 8 and lining the bolt holes The resent invention contemplates no special c ange in the mounting or insulating of' the bolts, so for illustrative purposes there are shown, in the figures of the drawings referred to, the conventional oint bolts having the usual heads and nuts 6 and 7, at the inner sides of which are arranged the insulating washers 8 and the metal backing washers 9 interposed betweenthe insulating washers and the heads and nuts of the bolts. In this form of construction it is also preferable to associate with the joint bolts, insulating bushins 10 adjoining the inner faces of the and each of the same is of the type commonly characterized as a reinforced angle bar wherem definlte provislon is made for strengthen 1ng,-trussing and reinforcing the angle bar in Y the vertical plane of the joint between the meeting ends of the service or running rails. In the form of rail oint shown in Figs. 1 to 5 inclusive of the drawings, each of the reinforced angle bars 3 and 4 is provided with the usual main splice bar portlon 11, and with the head and foot flanges-12 and 13, res ectively cooperating with thehead and ase of the rail. In addition to these elements each'of the angle bars is rovided at a point intermediate its ends with a centrally arranged pendent reinforcing leg 14 preferably formed integrally with the foot flange of the bar and projected downwardly from the outer edge of the said foot flange. The reinforcing leg 14 is arranged beyond the edge of the rail base or base flange and extends a distance below the bottom of the rail base to effect a stiflening and reinforcing of the intermediate portion of the angle bar extendin over the ointbetween the meeting ends 0 the rails.

These are the functions of a reinforcing leg projected downwardly from the foot flange, of an angle bar intermediate the ends of t e latter, and in the particular form of joint described, the reinforcin leg 14 of'each an le bar not only projects be ow the plane of t e bottom of the rails or rail basesfbut also is deflected inwardly at an ahgle beneath ,the rail bases, as plainly shown in Fig. 2 of the drawin s. In adapting the sectional or twopart rai supporting base to this construction, the separate'base plate sections 15 and 16 are respectively su ported on and carried by the reinforcing Iegs 14 of the opposite angle bars. In one form of construction that may be advantageously employed, each base plate section 15-and 16 is formed with a main orizontal flat body portion which provides a supporting seat or rest for one rail end,

and at one end the said body portion of each" base late section has bent therefrom an angular y or obliquely disposed supporting 'flange 17 which conforms to the inclination of the reinforcing leg 14 with which it is associated. In the construction shown in Fig. 2

of the drawings the angularly or obliquely,

disposed supporting flange 17 of each base plate section 1pro ects below the plane of the top portion 0 the plate from which it is bent and is deflected inwardly toward the'l-ongitudinalcenter line of the rails, so that in the assembling of the several elements, each base plate section 15 and 16 has its pendent'inwardly deflected and oblique supporting flange 17 arranged flat 'uponithe innenside of the reinforcing leg 14 of one angle bar and secured rigidly to such leg by means of rivets, bolts, or equivalent fastening devices '18.

This construction makes each .base plate other base plate section is supported on and. fastened to the diagonally opposite end portion of the reinforcing leg 14 of the oppositev plate section 15 and 16 may be made of any suitable length so, as to extend entirely or only partly across the bottom of the rail bases, but in all constructions and forms each base plate section is arranged to receive thereon one rail end only. Also, in carrying out the invention the reinforcingleg 14 of each angle bar may be of any desired or pre-v ferred length, but in the type of rail joint construction shownin Figs. 1 to 5 of the drawings, the said reinforcing leg 14 ofeach angle bar is illustrated as being of a length equaling and slightly exceeding" the combined widths of the two base plate sections 15 and 16, thereby contributing materially to the effective stiffening and'reinforcing of each angle bar at both sides of the. meetin point-of the rail ends.

It is to be further noted in the construction described, that the pendent reinforcing legs. 14 of the opposite angle bars are located wholly in a lane between the opposite tiesT above whic 1 the end portions of the angle bars lie, so that the separate oppositely related base plate sections have no direct suport on the ties, while at the same time there 1s a direct bearing of each rail on a metal base plate section, and the load applied to the joint is not deliveredto the ties directly but through insulation.

The insulating" of a joint constructe-d as p described can be effectedvery thoroughly by the simple insulating ex edients of utilizing 65 side insulating sheets 19 etween the sides of embody the present invention is shown in and fastened to one end portion of the reinforcing leg 14 of one angle bar, while theside of its lower edgewith a reinforce rib end.

the rails and the rail adjoining faces of the angle bars, and having an insulating end post 20 between the railends Which'is arranged to' have its base 21 project below the plane of the rail bases 'so'as to lie interposed etween the inner s acedadjacent edges of the separate base p ate sections 15 and 16.

Another formofrail joint of the reinforced angle bar type, which may be reorganized to Figs. 6, 7 and 8 of the drawings. In this 7 construction, each angleibar 22 and 23 is pro: vided with the usual head and 'foot flanges 24 and 25 respectively, and the foot flange 25 thereof is formed intermediate its ends with an integral rail clasp 26 adapted to clasp over the edge of the base flan e of the rail; The rail clasp26 of each ange bar 22 and 23 in efl'ect, constitutes a bottom reinforcing extension which is .formed below the plane of the rail base with an inwardly extending horizontal rail supporting or base blate section 27 presenting a fiat supporting shoulder or .face upon which the rail base rests. In this construction the inwardly extending base late section 27 of each angle bar has bent om its inner ed e a pendent vertically disposed reinforcing eg 28 which itself is stiffened by forming the same at the inner 29. The distinctive feature of the form of joint shown in Figs. 6, 7, and 8, resides in preserving the same two-part or sectional ase plate arrangement as embodied in the form of joint shown in Figs. 1 to 5 inclusive of the drawings. To provide for this the re' inforcing legs 28 and the base'plate sections 27 ofthe opposite angle bars are arran ed in staggered. or diagonally opposite re ation whereby the base plate section 27 of one angle bar is arranged to extend beneath and support one rail end, while the base plate section of the opposite angle bards arranged-to extend beneath, and support the other rail In this arrangement the same mechanical functions are preserved as in the form of joint already described, while the insulation of the jointmay be effected in the same way, viz: through the employment of the'side insulating-sheets 19 and the insu-- l'ating end post 20' previously described. Also, the joint bolts and joint bolt insulationmay I remain the same as described, and hence, similar reference characters will apply to similar parts in Figs. 1 to 8 inclusive;

Another variation'of the invention is suggested in Figs. 9 to 11 inclusive of the'draw ings wherein the sectional ortwo-part base construction is shown ap lied to a rail joint having reinforced angle plendent reinforcing legs disposed vertically. eferring particularly to this modification, the reference characters 30 and 31 designate a the o posite angle bars, each of which is'pro-s vide at the outer edge of its foot flange 32 136 ion" ars provided with with a pendent vertically dosposed reinforcing leg 34, and to the inner side of the leg 34 of'each angle bar is riveted,bolted, or otherwise suitably fastened, as at 35,. the angularly disposed sup orting flange 36 bent downwardly from t e outer edge of a base plate section. v The separate base plate sections are designated respectively by the numbers 37 and 38 and preserve the same relative arrangement as the base plate sections shown in the other views of the drawings. However, in this form of the invention, as well as in the form shown in Fig. 7 of the drawings, the individual base plate sections are illustrated as extending only partly across the bottom of the rail bases, while at the same time preserving the spaced parallel relation of the separate base plate sections so that each base section receives and supports thereon one rail end. Also, in the form of the invention shown in Figs. 9, 10, and 11 of the drawings, there is su gested the idea of having each reinforcing eg 35 of a length substantially equaling the width of the base plate section supported thereby, so that not only the base plate sections, but also the reinforcing legs of the opposite angle bars preserve a diagonally opposite relation. To provide for insulating the joint shown in Figs. 9 to 11 inclusive, the same insulating expedients already described may be utilized, viz: 'side insulating sheets 19 and the insulating end post 20 interposed between the rail ends.

H A further adaptation of the invention is illustrated in Figs. 12, 13, and 14 of the drawings. In these figures of the drawings a joint is shown involving the opposite side angle bars 39 and 40 each of which is provided with a foot flange'41 having formed integral with its lower edge, intermediate the ends of the bar, the integral horizontal base plate section 42 and at the outer edge of said ase plate section with a reinforce flange 43. 4 .The base plate section 42 of each of the angle bars 39 and 40 extends horizontally beneath a rail base and is disposed in diagonally opposite relation toithe base plate section 42 of the opposite angle bar. .This construction preserves the spaced parallel relation of the two base plate'sections in diiierent transverse planes so that each of said sections su ports directly thereon one rail end-only. n this respect the two-part base plate arrangement 55 is the same as involved in all other forms of the invention and specifically is substantially the same as the base plate arrangement shown in the group of Fi s. 6 to 11 inclusive of the drawings. It wil be observed that the 60 modification shown in Figs" 12 to 14 inclusive involves the feature of locating the base plate of each angle bar at one sideof the transverse center of such angle bar, but by reason of thediagonally opposite relation of the separate base plate sections, there'is a' gested a modified insulating expedient that may be em loyed in this and in all other forms, viz: t at of using what may be termed a one end insulation for each angle bar, which one end insulation consists of a sheet 44 of insulating material interposed between one endportion of each angle bar and one rail end, the insulating sheets 44 for the op osite angle bars being disposed in diagonal y opposite relation. This gives a direct metallic bearing of the joint with the rail throughout half the length of the joint without the interposition of soft relatively compressible material, while at the same time economizing insulating material and effecting a complete insulation of the joint in connection with the joint bolt insulation and in connection with the end post insulation 20 previously described.

The modification of the insulation, as shown in Figs. 12, 13, and 14 is necessarily applicable to all of the other forms of the invention herein described. v

Various other modifications of the invention will readily suggest themselves to those skilled in the art and it will'beZ-understood that various changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
